skilled in the art to which it appertains to' make and use the same.

The object of this invention is to provide a perpetual or continuing calendar adapted for adjustment from month to month and year to year, and limited in range of usefulness, if at all, only by the year designator, in that the month, week and day designations may be varied to suit any conditions which may arise and with the minimum of efi'ort and loss of time on the part of the operator, and with this object in view the invention consists in the construction and combination of parts of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1 is a front view of the calendar.

Fig. 2 is a rear View of the same.

Fig. 8 is a transverse section on the plane indicated by the line 33 of Fig. 2.

Fig. 4 is a detail view of the day indicating slide showing the front thereof.

Fig. 5 is a similar view of the day inclicating slide showing the rear thereof with means for concealing superfluous day designations or dates.

The device consists principally of a base 10 which may be a suitable card or plate, provided with a group of openings 11 for the exposure simultaneously of the day designations of any given month, the horizontal sets or series of these openings being respectively designated by the days of the week arranged as shown in a column 12 as at the left of the group of openings. Also at one side of the space occupied by the said group of openings may be arranged an opening 13 for the inclosure of a month designation, the names of the months being carried by a slide 14 fitted adjustably in a guide 15 extending from the rear surface of the base or board, while at the opposite side of said group of day openings may be arranged spaces 16 for the exposure of numerals representing the year, each numeral being carried by a separate slide 17 mounted in a guide 18 as shown in Fig. 2, and each of said slides has a series of numerals so that any of a day indicating slide 20 having represented thereon a group of numerals carried in columns and spaced to correspond with the openings 11 in the board or plate, said slide being adjustable to arrange the proper portion of a group of numerals for exposure through said openings 11 to correspond with a true calendar, or in other words to arrange the numeral 1 of said group oppositethe week designation corresponding with the month of the year for which the calendar is set. It will be. noticed that by means of the adjustment of the slide all of the possible combinations in designating the days of the selected month may be fulfilled, and in order that those numerals of the group represented on the slide which are superfluous in any month such as those representing the thirty-first day or the thirtieth, twenty-ninth and thirty-first for February, or the thirtieth and thirty-first for February leap year may be concealed so as not to cause confusion in reading the calendar; the slide 20 is longitudinally slotted as shown at 21 to form intervening guide strips 22 upon which are mounted auxiliary concealing slides 23 either or both of which may be moved as required to cover the superfluous day indicating members so that they may not be exposed through the openings 11 in the plate or board. Owing to this construction the arrangement of the openings 11 may be made to suit all conditions which may arise in connection with monthly calendars without necessitating separate month slides or a variable arrangement of the week day designations.

It will also be noticed that the adjustment from month to month involves merely the changing of the month slide and of the week day designating slide together with such supplemental adjustment of the auxiliary slides as may be necessary to conceal the superfluous numbers.

What is claimed is 1. A calendar comprising a base provided with a group of openings for the exposure of the day designations of any given month arranged in vertical and horizontal rows, parallel rows of openings having day designations associated therewith, a day indicating slide mounted on the rear of the base and provided With a group of day indicating numerals arrangedin vertical and horizontal rows to register With the group of openings in the base for exposure therethrough, said slide being movable on the base in line with the day designations, and concealing slides mounted on the day indicating slide to cover surplus numerals thereof.

2. A calendar having a base provided With slots, a slide movable across said slots and having day indications for exposure therethrough, a slide disposed laterally of said slide having year indications, another slide disposed laterally of the first slide having ROBERT A. ALLYN, H. A. VALLEE.
